Title: An instrument for locating particular cutaneous points caused by viscero-vascular reflex
IPC: A61B5/053

Abstract: 990,296. Diagnostic apparatus. TATEISI DENKI KABUSHIKIKAISHA. Sept. 11, 1962 [Sept. 27, 1961], No. 34714/62. Heading A5K. An instrument for comparing the impedance of skin of a patient under heat with the impedance of normal skin in order to locate cutaneous points caused by the viscerovascular reflex, comprises indifferent and explorer electrodes 5, 6 for contacting the skin under test, a circuit 4 simulating a normal skin layer with respect to impedance or including a normal skin layer, a circuit for comparing the impedance of the skin under test with the impedance of the normal skin layer or the skinsimulating circuit and a source of alternating current. The circuit 4 and the skin under test between the electrodes 5, 6 are disposed in arms of a bridge circuit which also includes equal fixed resistances r<SP>1</SP>, r<SP>11</SP>. Alternating current from an oscillator 7 is supplied to the bridge circuit. When the bridge becomes unbalanced due to the differing impedances of the normal skin or skin-simulating circuit and the skin under test, the degree of unbalance is indicated by headphones 13 or a speaker, or an ammeter 12. The circuit is housed in a casing 14 having at one end the indifferent electrode 5 for grasping by the patient and at the other end the explorer electrode 6. The explorer electrode includes a roller portion 6 1 , which in use contacts a relatively large skin area and is used in finding the general area in which the cutaneous points sought are located, and a pointed portion 6 2 , which contacts smaller skin areas and is used for locating the individual cutaneous points. An alternative direct current source may be used with the roller portion of the explorer electrode. Two circuits (Fig. 4, not shown) simulating the impedance of the skin may be arranged in parallel in the bridge circuit, one being connected in circuit when the roller portion of the explorer electrode is used and the other being in circuit when the pointed portion is used, the two circuits correcting for the capacitance of the roller portion and the pointed portion, respectively.

Filed: 1955-12-06
Abstract: 782,967. Shearing. PETIG, H. Dec. 6, 1955, No. 34908/55. Class 83 (4). [Also in Group XXVIII] A fluid-operated wire cutter is supplied with fluid to its actuating cylinder 1, Fig. 1, by a hand pump 5 having two pistons 11, 12 sliding within one another and so arranged that only the smaller piston 11 is actuated when the pressure on the cutter blade 4 builds up. The pump 5 has an inlet valve 30 from a chamber 28 and an outlet valve 22 through which fluid passes via a channel 21 to the cylinder 1. The smaller piston 11 is coupled directly to the pump lever 6 through a link 8 and a slide 9 and for quick pumping at low pressure the lever 6 is moved through a full stroke so that the slide 9 engages the larger piston 12 and moves it against the pressure of its return spring 17. On build-up of pressure the lever 6 is moved through a limited stroke to actuate only the piston 11. A connection 48 is provided on the pump body 5 for actuation from an external supply. The fixed cutter 46 is laterally slotted to accommodate the work and is adjustable by threaded rods 47 in a holder 38 which is pivoted about a pin 32 for insertion of the work. During cutting the holder 38 is locked in position by an arm 39 which engages projections 41 on the cylinder 1. A spring-loaded plunger 43 supports the work against tilting during cutting and ejects the severed work. The pin 32 carries wheels 33 on which the cutter is moved by means of a handle 34.

Title: Improvements in machines for dividing or cutting toffee, caramel or like material
IPC: A23G7/00
Filed: 1935-12-20
Abstract: 467,593. Cutting caramel &c. WHITEFIELD, B., and BAKER PERKINS, Ltd. Dec. 20, 1935, No. 35301. [Class 87 (ii)] A sheet of toffee, caramel, &c. is fed continuously against spaced cutting knives or discs, the resulting strips being spaced fanwise and fed in the direction of their length to transverse cutting means. The transverse cutting is effected by a series of vertically reciprocating knives that are also reciprocated in the direction of their length and travel at the same speed as that of the strips. In a modified arrangement, the transverse cutters are arranged on endless chains, the lower runs of which are inclined to the horizontal path of the caramel strips. The knives carried by the chains travel with the strips and are reciprocated transversely to the direction of the strips. Means is provided for preventing the strips from sticking to the cutters, and for breaking the partially severed tablets from the strips. The sheet 11, Fig. 1, of caramel &c. is cut into longitudinal strips 12 by spaced rotating discs 10. The outer strips 12a are rejected by guides 14, and the strips are spaced fan-wise, as shown, by spaced discs 15 on a shaft 16. The strips pass over flat-topped bars 18 on the table of the machine and between partition members 21 carried by the transverse cutting mechanism. The knives 33, Fig. 3, are adapted to be reciprocated in the direction of their length between transverse bars 54 and over notches 56 in the partitions 21. In use, the reciprocating knives and partitions descend and cut the strips of caramel while travelling therewith. When the knives are raised, the severed or partially severed tablets are prevented from sticking to the knives by transverse bars 54 arranged over recesses in the partitions 21. The tablets are separated by blows from spring-actuated fingers. The cutter head is then moved backwardly to engage a fresh portion of the uncut strips and through a distance greater than that between the first and last knives 33. In the form shown in Fig. 7, the strips of caramel &c. fed between rollers 172, 173 over a table 123 having an inclined part 123a are cut by knives 119 carried between endless chains that are reciprocated in the direction of the axes of their driving sprockets. The chains are carried in a casing 113 provided with means for ejecting the cut tablets over the edge 123b of the table and comprising a bar adapted to be passed between successive pairs of knives after they have effected the cutting operation. The casing is pivoted 114 for cleaning purposes.

Title: Process for the production of glycols
IPC: C07D301/10
Filed: 1966-08-09
Abstract: Production of a glycol from an acyclic olefin by oxidizing the olefin at elevated temperature with oxygen or an oxygen containing gas in the presence of a catalyst, controlling the temperature of the reaction by cooling the reactor with a fluid, separating the resulting olefin oxide, hydrolysing the separated olefin oxide to give a dilute aqueous glycol solution, and finally concentrating the dilute aqueous glycol solution utilizing as a source of heat the fluid heated during the step of cooling the oxidation reactor. The separation of the olefin oxide is preferably effected by contacting the effluent from the oxidation reactor with a suitable absorbent, e.g. water, and subsequently stripping the ethylene oxide from the absorbent with low pressure steam which may be formed during the subsequent step of concentrating the dilute aqueous glycol solution. The fluid used for cooling the oxidation reactor is preferably a hydrocarbon liquid which boils in a narrow range around 232 DEG  C. under a pressure of about 1.15 atmospheres. The preparation of ethylene glycol from ethylene is exemplified.
